The rich may be different from you and me, as F. Scott Fitzgerald once noted, but bankers are increasingly different from the rest of the rich. In this year’s election, Wall Street’s campaign contributions and voting patterns, as best we can discern them, bear no resemblance to the contributions and votes from our other most highly paid sectors — particularly high tech.

A cruise through two haunts of the rich — the techies’ Silicon Valley and the banker towns of Connecticut’s Fairfield County — turns up strikingly different voting patterns. President Obama carried Santa Clara County, the epicenter of high tech, by 43 points over Mitt Romney. In such leafy Wall Street burbs as Greenwich and New Canaan, Conn., by contrast, Romney prevailed by 11 and 29 points, respectively. Outside the most banker-dense villages, Romney’s totals plummeted: Obama carried the whole of Fairfield County by 11 points, much as he carried most of the affluent suburbs of New York, San Francisco, Washington and Los Angeles.
